Specification of Letters Patent.

Application filed November 10,- 1909. Serial No. 527,315.

To all whom a may concern:

Be it known that I, WILLIAM BENNIE 'PATRIGK, a citizen ofthe United States, re-' sidin at Woodland, in the county of- Yolo and tate of California, have, invented certain new and useful Improvements in Air Purifying and Distributmg Apparatus, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain new'and useful improvements in air purifying and distributing apparatus which is adapted more (particularl for ventilating the rooms of a Welling, 0 cc, public buildin or the like, whereby a constant supply of resh air may behad, the process of purification killing and removing all germs from the air currents.

Another object of the invention is to provide a refrigerator in connectionwith the air supply chamber, pipes extending from said chamber into the refrigerator and ada ted to maintain a constant, circulation of resh air through the same.-

A further object is to. provide a blower.

adapted to discharge air into a water tank, a suitable screen or straining device bein' located in said tank through which the air currents are'adapted to pass from the water into the air supply tank, said tank having removably located therein a salt bag so that the air becomes surcharged with salt'before it is carried therefrom and utilized.

With these and other objects in view,the invention consists of the novel features of construction and the combination and arran ement of arts hereinafter fully descri ed and claimed, and illustrated in the accompanying drawings, in which Figure 1 is a vertical longitudinal section of an apparatus embodying my invention;

Fig. 2 is a top plan view; Fig. 3 is a'hori zontal section .on the line 3-3 of Fig. 1; and Fig. 4 is a detail'perspective view of the stralning sieve.

Referrin to the drawings, 5 indicatesa substantial y rectangular tank which is formed with the hollow walls 6. Charcoal or other non-conductin material is disposed in'the hollow walls of t e tank. The tank is preferably formed to provide two compartments, and is divided by a centraltransverse' hollow wall 7. This wall has open communication with the side walls of the chamber and also receives the non-conducting mateand to the a paratus is controlled by the valve 19'- is interposed pipe and is adapted'to regulate the supply rial. The chamber 8 is adapted to receive a supply of water from thesupply pipe 9, and a fan or blower'lO of any preferred form is also adapted to discharge air into the water through the pipe 11 which extends therefrom. Supported within the upper end of the tank is a housin 12. The eater part of the bottom of thls housing is cut awayto receive a strainer or sieve 13. This strainer is angularly disposed and through one end and thetop thereof the water and air supply pipes 9 and 11, respectively, extend. As shown in detail in Fig. 4, this strainer comprises a top, side walls, and one end wall, the outer end and the bottom of said sieve being open. A transverse wire mesh 14 extends between .the sides of the strainerat its outer end, and a plurality of similar straining members 15 are arranged in spaced relation between theends of the strainer. The other end of the member 13 is supported upon the short bottom wall 12' of the housing 12'.

A pipe '16 extends through the top of the housing and is adapted to carry off the supply of air which is discharged mto the same mm the water after assing through the various straining mem ers carried by the sieve. -This air 1s conducted to a chamber which would preferably be located out-doors to receive the rays of the sun, or, if desired, may be heated by artificial. means. During the passage of the air through the pipe 16, it becomes thoroughly dry and is returned through the pipe 17 to the apparatus. The pipe 17 extends downwardly Into the tank or chamber 8 and is coiled, as shown at 1% transversely therein. The air becomescoole during its assage through this convoluted portion of t e pipe which is disposed in the base of the tank and subjected to the cooling action of the water; The supply of air from valves 16" an '17'-,respective1y.-"-After passing through the coil 18, the ipe is vertically extended throughthe top 0 the housing and thenlaterally turned as shown at 19. A in this portion of the of the purified air which ows through the pipe and isconducted to the various a artments of the residence, school, hospita' or other public building. In Fig.1 I have shown a salt bag 20 removably disposed within the housing 12. The air in ascendin into the housing contacts with this'bag an absorbs the salt properties thereof, thus pro- Q ducing salt air. The degree of salt contained in the air may be regulated by the size of the bag. When it is desired to carry the air directly ofi from the housing 12 to the rooms of the building without its passing through the drying pipe 16, the valve 16 is cut off and the air will then be exhausted from the housing through the pipe 21 in which a valve 21 is located. pipe is connected at any convenient point to the pipe 19 from which the air is distributed.

In the other of the chambers 22 of the tank 5 a refrigerator or provision box 23 is adapted to be arranged. This refrigerator is also formed with hollow walls 24: similar to the walls of the water tank.- Vertical plates 25 are secured within the refrigerator etween which the shelves 26 are arranged,

and receive thereon the various provisions. Extending through the central transverse wall 7 of the water tank there is a pipe 27 which conveys Water from the tank 8 into the chamber 22. rounds the refrigerator which is placed 1 therein and keeps the contents cool and fresh. A pipe 28 also extends from the housing 12 and is adapted to conduct the air therefrom to the interior of the refrigerator. This air is kept in constant circulation and is exhaustedthrough the short pipe 29 secured one of the hinged cover sections 30. The upper end of this pipe has secured there- 'to a wire mesh 31 whlchprevents the entrance of flies or other insects to the interior of the provision chamber. A cord 33 is secured in eyes on the top of the refrigerator by means of which the same may be lifted from the chamber 22 .(after disconnecting the pipe 28 from the housing 12) when it is desired to scour the same. In this manner,

the contents of the refrigerator may be preserved for an indefinite time, and a constant carried into the various dwelling rooms.

From the foregoing it will be seen that I have produced an air purifying and distributing apparatus of comparatively simple construction. It is ada ted to be installed in the basement of the uilding and is admirably adapted for use in such institutions as hospitals, sanatoriums, and large oflice buildings. It will also be found a great convenience and benefit for rivate use. The various elements employe in itsconstruction are of sim is form and compactly arranged so that t e entire apparatus will occu but little space.

ile I have shown and described what I believe to be the preferred embodiment ofthe invention,- it will be understood that various minor modifications may be resorted to without de arting from the essential features or sacri cing any of the advantages of the invention.

This

This water entirely s'ur-' If desired, an electrode 34 may be positioned in the main water tank 8 whereby the water may be charged to destroy the germs entering therein through the air pipe 11. This electrode may be wired in any desired manner to a suitable source of electromotive force.
